Jim Wolf Cam testing for the VQ37VHR -- Results inside!

PongSanity · 09-25-2015, 03:31 PM

a very worthwhile mod. would look into this whenever the time comes for a motor rebuild.

There isnt more lift on one side of the head, the cam is offset on the bucket and runs at a different ratio in order to retain the same timing equipment as previous vq engines. It was cheaper for nissan to make one different cam than to make all new length chains and alter the disign of the block. The vvel is different on each head for the same reason one appears to have more lift than the other. But is actually the same at the valve. Also @ MA Motorsports whats up ray?(unsure who's managing forum duty) i spoke with you a few years ago at the FD of long beach when the shiz happened with essa. Had a bunch of life crap happen. Im working on a new vk56 project will call the shop next week.

So your saying that the CAMS ARE ACTUALLY different and this needs to be taken into account by aftermarket?

Spot on, and this is Daelen but I will get the message over to Ray! Holler if you need any VK info, we are always working on some fun stuff with those.

Jim wolf is very aware of the situation and this was taken into account. The OE measured the lift from the "base circle" of the cam, and JWT based the design off that also. So the lift/duration does not vary from side to side but the base circle will, the same as the OE. All due to the VVEL system and how Nissan set up the heads.

Edit: also at seb my old car is still holding strong with the drysump and ati balancer new owner may be interested in doing 500bhp 9000rpm. Im doing a custom rpm rollbar in it(which fit like **** btw) and i know we already have the airflow so i will give you a call next week as well. hes out your way in ojai and i am way too busy to do it.

Sounds good. Hope all is well.

Also just for future search's:

For the DLC coating on the cam buckets, the 2009 model year for the G7 and 370Z was the only year that some cars came with a motor that did not have the DLC coated exhaust cam buckets. These will need to be purchased to do the install due to how the cams are designed tolerance wise. So make sure you or your installer are aware of this when opening the heads.

These are a mild 263* cam, so as you can see we have more room to make some power with a cam that is more aggressive.

Is there a way to find out if.your car didnt come with the dlc coating?

Sadly at this time there is not. After going over all the info Nissan offers in FAST there is not one distinguishing factor other than the model year 2009 (Ends in September for Nissan, and October for Infiniti) So if you have a 2009 and want to prevent down time ordering the buckets is not a bad idea. Otherwise most dealerships can get them asap(As can we)

List is $21.63 each(12 needed) so expect around that but a little cheaper normally.

Ok thanks

Also Daelen i noticed after having to describe it in another thread but the initial write up you had on the first page you state to "re-place" the vvel components on the back of the head but it should be clarified so there is no confusion that there is a lengthy not so well described process in the fsm for aligning the control shaft to the actuator and motor, and then for aligning the sensor and actautor once back in the car that should be followed to prevent timing/vvel errors/strange running behavior once reassembled. I just wanted to throw it out there due to the number of times i've seen someone service the cams only to run into problems at startup and have to tear it all apart again to fix it. I'm sure you guys did it but it is often overlooked in the whole process.

You are 100% correct on this.

This post was meant to be a "Hey, this is the REAL BASIC run down of what we had to do" so people didn't have to scroll through all 1500 pictures I took of it haha. Its a very detail oriented task for sure.

If I already have headers, will I still see similar gains on top of what i already have? Now I am pretty excited to see stage 2 paired with an improved intake manifold that several groups are working on. If they work together for good gains, I might have to give Sebz some more money.
